## NAME

Clutter::Behaviour::Scale - A behaviour controlling scale

## SYNOPSIS

```
    my $behaviour = Clutter::Behaviour::Scale->new(
        Clutter::Alpha->new($timeline, 'ease-in-quad'),
        1.0, 1.0,       # initial scaling factors
        2.0, 2.0,       # final scaling factors
    );
```
